You will not get full effects if your cell phone is not stereo. Not sure what phone you have. I have an iPhone 6 and it tested 20khz+ with audacity. So frequency is good but there is only one external speaker so the two stereo channels are combined and played through the one speaker. So long story short yes there is a loss effectiveness. I only play subs this way when I have no other feasible option.
